LK11 Y/R U is Altech Corporation’s yellow/red door interlock handle for LK11-series motor-disconnect switches. Its retention mechanism rotates 90 degrees from off to on and keeps the handle in the off position while the cabinet door is open, enhancing safety during maintenance. The steel assembly is color-coded Yellow/Red and is padlockable with up to three 1/4-inch padlocks to secure the switch in the desired position; it is designed for shaft interfaces compatible with LXXXAD11 (shaft-only) configurations. This variant carries UL Type 4X (IP67) environmental protection, making it suitable for demanding industrial environments.
